摘要: An entrochemical energy transfer system and a related process for obtaining work from environmental thermal energy are disclosed. In one example, a plurality of linked entrochemical cells with nested chambers provides an aggregate thermal gradient of each entrochemical cell by transferring environmental thermal energy in and/or out of the plurality of linked entrochemical cells. The aggregate thermal gradient generated from the plurality of linked entrochemical cells can be utilized as an environmentally-friendly energy source for human needs. The entrochemical energy transfer system and the related process for obtaining work from environmental thermal energy utilize a set of entropy transfers from Earth's day and night thermal energy inflows and outflows. Furthermore, in one example, the process for obtaining work from environmental thermal energy involves two steps, each step resulting in entropic increases and transfers.
